5 Cleaning and maintenance

•To clean the unit, wipe with a soft cloth dampened with water. Don’t use a cleaner or solvents on the unit; they can damage the case and leak inside, causing permanent damage.

•Battery contacts may be wiped with a dry lint-free cloth.

•If the unit gets wet, turn it off and remove the batteries immediately. Dry the battery compartment with a soft cloth to minimize potential water damage. Leave the cover off the battery compartment overnight or until completely dry. Do not use the unit until completely dry.

6 Disposal of the device

At the end of the product lifecycle, you should not throw this product into the normal household garbage but bring the product to a collection point for the recycling of electrical and electronic equipments. The symbol on the product,

Some of the product materials can be re-used if you bring them to a recycling point. By re-using some parts or raw materials from used products you make an important contribution to the protection of the environment.

Please contact your local authorities in case you need more information on the collection points in your area.

7 Using a PMR device

To communicate between PMR devices they need to be set all on the same channel and within receiving range (up to max. 6 km in open field). Since these devices use free frequency bands (channels), all devices in operation share these channels(total 8 channels). Therefore, privacy is not garanteed. Anybody with a PMR set to your channel can overhear the conversation. If you want to communicate (transmitting a voice signal) you need to press the PTT -button.

Once this button pressed, the device will go into transmit mode and you can speak into the microphone. All other PMR devices in range , on the same channel and in standby mode (not transmitting) will hear your message. You need to wait until the other party stops transmitting before you can reply to the message. At the end of each transmission the unit will send a beep. To reply, just press the PTT -button and speak into the microphone.

If 2 or more users press the PTT - button at the same time the receiver will receive only the stongest signal and the other signal

(s) will be supressed. Therefore you should only transmit a signal (press PTT - button) when the channel is free.
